Hi Marcin,
Sounds rather unlikely to me. Its likely handled at an upper layer (vfs in linux' case) and only overloaded when an
optimizedimplementation is available.
Which os do you see implementing that only on a part of the filesystems?
A runtime check would be creating, fsyncing and deleting a directory for every directory youre fsyncing because they
couldbe on a different fs...
